Mv-Nsss'ss [M 2 f V y-w illmmt'kiiiiwh "that 1", A S KELLY, a citiz'e ofihe UnitedStatesfresiding' at the city of Providence, county of Rhode Island, have and useful 1m of Providence, State has, of which the' follow lng'isa specificatl g My' nvention ela es'to ajnair cooling and humid fymgnpparatus, ifl hd ls an improve mentj upon the" apparatus shown and de- 7 scribed hettersl 'atent of the United StateQNo. 787,454, issued to me April 18, 1905, and is designed: generally to perform the saine functibns, but embodies novel features of construction andoperation adapted to; ei'fform the desiredfunctions in alpioreper ect manne'fthan are performed by the/apparatus of the patent.

My 1. present invention aim s' t'o provide an ineror a ms r i in pl moistureto't e atmosphere of cotton-mills, .factories, and the like and wherever it is desirable to artificially moisten the atmosphere.

Still furtherebje'cts of my present 1nvenv: tlon are toprovide a novel filtering structure arrangedito permitjof ready removal of filter parts means, to regulatethesu'pply of water and to the filters,and means to regulate the flew of waterfrqrn the filter, whereby a I perfect d ischargeof either a hotor' cold vapor or the. distributr may l eeflected. Thi apparatus is especially ada ted for therbomsmjmius, wherein the air is 'able to become. vry dry'orjfullof dust of fibers in a consequenceof employment of manufacturing. 'rocesses,;. which are detrimental'to the hell H1 01 Gomiort-ofthe workmen. In thev accompanying sheet of drawmgs, Figure-1i represents a side elevation of my improved air cooling. and humidifying apparatus, as secured in. operative position on the,ce1l1ng, of a mill-room.

Like reference characters rindicate like partsw" The body of my improved apparatus is in the form of a casting A adapted to be secured to the ceiling of a mill-room, by bolts (4, a, and this body of theapparatus has tubular portions 6 and'c, which'provide respectively Water and air passages. These tubular ortions curve over each other and have t eir lower ends screw-threaded,to engage with shut-off cocks of the apparatus. The upper ends of these tubular Lortions and c termi- 'nders d and e, which are each arranged to receive a filter, Each tubular portion 1) and c is in open communication with the interior of each cylinder (1 and e, and beyond each cylinder and centrally "thereof, is arranged ahead f and a tube 9', and betweensaidhead and said tube is a vertical extension h, which is provided with a small water duct or port i.

Y My improved filters are constructed alike andof equal size, and each filter comprisesa frame made of tin or other suitable light material, said frame having a closedbody portion j integral with outer longitudinally arranged stri s j 7' to contact upon the peripheral sur ace of the cylinders, and on this frame and strips is secured layers of wire gauze 74'.

Each filter, as described, is in the form of a fivepointed star, in cross-section", as shown, and each filter is secured within each cylinder d, e, by a ca Z which is provided with a. screw-threaded portion to engage thereby with the threaded open end of each cylinder,

in the manner shown in 'Fig. The bod portion 1' of each filter-frame is provided with a small 'openi m for the reception of a hook or other suitab e instrument to withdraw the filter from position, Whenever the latter has to be cleaned from sediment. M p

In the head f of the body A is mounted a tubular support n. i A needle-valve-stem 0 is movablein the .head f, and said stem has a conical point 0 which acts asa valve to bear' against mclosing a seat 0 of a duct'oi' port p communicatin withthe chamber of the.

water-filter. p with a fine screw-threaded; ortion o to enhevalve-stem 0 is provided gage thereby with the threa ed interior of the tubular su port at, which is sec'uredin; the

head f oft e body A. Be ond the-valve 0" of the stem 0, and contra y of the duct or a port Lin the vertical extension h, is formed a a -made tofit the openingre circularrecess to receive awasher q of felt or other suitable. absorbent material. This washer is located below the needle-valve p and above-said valve is secured. aplugr,

recessfor the Washer q and ducts.

"Shut-ofi cocks 8, s which are mounted 'on' .the lowerends'of the tubular portions band c of the body A, have their valve stems 8 ,8 "arranged'in longitudinal alinement with each other.,-and each. stem has its outer portion made flat, as ats s in Figs. 2'and3, and on these flattened ortions of the stems is secured'a divide sprocket wheel thy bolts am. An endlesschain o is mounted on-the wheel i and of a'length 'to come within easy reach to be pulled upon in regulating. the

opening or closing of the cocks. A .s rocket wheel to is secured upon the outer en of the needle-valve-stem 0, and this wheel is also provided with an endless chain a: to operate the needle-valve; .Branchpipes y,j y con-' nect with the cocks s, s, andfrom the tubeg' of the y P p lefldS t0 the vapordistributer z.

The operation of the apparatus is as follows: Referring to Fig. 2, a pull u on the chain '0, of the sprocket t, opens'bot cocks simultaneously, and eri'nits the water and air to pass through t e passages band '0 ofthe body A andthrough the screens k, k oi the filters. The valve 0 is moved slightly from its seat, by means of'the chain connection x with the sprocketw, and as the water.- leaves its filter, in the direction indicated by the arrow in Figf'2', it passes through the duct or port 10 and percolates through the .washer q, from whence .the Water falls in drops through the duct or port 2'. The water pressure is greater than the airpressure, consequently as the air passes through the tube g and meets with the drops of Water from the port .11 they are brought together and co-mingled at this point, as g in Fig. 2,

and from this point the Water and air is disdrop by drop through the duct or port i, and

thereby to obtain the pro er s ray or va or through the ipe y and istri uter z. he vapor distri uter 2 comprises a tubular member 2 whose lower. end is closed by a screw-threaded plug 2 and its up er 'end having an enlarged cylindrical head 2 disposing a circular bevel face 2 for the spray or va or to contact u on, and a collar 2' provide with a screw-t reade'dopening to engagethe threaded end of the branch pi e y, this opening being concentric with the evel quiredrto for'rn the having :anintegral annular hinge- 2 made fast-upon the circumferential surface ofthe head and provided withslotted openings 2 collar and-said head and these openings of a member 250i the distributerfacts as a rehasfor any re'ason not become subjected to the atomiz'ing process, and this drip-cup .may be readily. drained by removing "the having the filters star-shapedin crosssection disposes a large area of. screen surface to catch'anyforeign particles of dust or andat the same time the arrangement; of

"easily removed for cleaning,k by simply unscrewing the caps or covers l, [of the bodyA.

ter' su ply,"the' spray orva orcan be made either eavy or fine, as may e desired. for the conditions'existing theroofm.

By my construction andarrangemeiit of at the same time,an.apparatus that is com: paratively cheap-to manufacture. -f
